Nairobi Governor Johnson Sakaja has removed Geoffrey Mosiria from his position as Chief Officer for Public Participation, Citizen Engagement and Customer Service, a change communicated to City Hall staff on 21 October 2026.

The notice setting out the administrative reshuffle was issued by Nairobi County Secretary and Head of Public Service Machel Waikenda. Under the changes, Zipporah Njeri Mwangi, previously the chief officer for City Culture, Arts and Tourism, takes on additional responsibility for the public participation and citizen engagement docket in an acting capacity.

Mosiria confirmed his removal and, in an interview the following day, said he would contest the Nairobi gubernatorial seat in the 2027 General Election. He had already declared his intention to challenge Sakaja before the reshuffle was announced.

Speaking about the fallout, Mosiria invoked Robert Greene’s book The 48 Laws of Power, citing its first rule, which warns against outshining a superior. He suggested his removal was connected to his performance in the role, though no official reason was given for the change.

He also claimed that Sakaja had previously described him as one of the best-performing chief officers in the country, and shared an old video of the governor praising him at a public event. The praise, as described by Mosiria, has not been independently confirmed.

The reshuffle comes as Mosiria positions himself for a run against his former boss, placing the two men on a collision course ahead of the next election cycle. Whether the removal was directly tied to his political ambitions remains unclear from the available record.
